Of course, looking at Real Madrid's current strength, it can be predicted that they will be able to defend the Laliga title next season, especially since Barcelona is currently unstable, plus with a new coach, of course Barcelona needs to adapt to a new coach, and this takes time. So as you said, maybe next season no team will be able to compete with Real Madrid, especially in the race for the Laliga trophy.
Currently, there is nothing wrong with the squad. The current players are what the team still need to defend their Laliga and Champions league title next season. No one to be removed and not even one to bring in unless they want to have a replacement for some of the players because of injuries or any future casualties.
In the meantime, Vinicius Jr and Bellingham are all doing great in the tournaments going on (Copa America and Euro 2024). They are the two players who are the top in receiving the Ballon D Or. I want to believe that if they if Real Madrid can defend their titles, they will continue to remain the best team in the world.
I love the enthusiasm for Militao, Rüdiger - they're winners. Still, folks, Alaba's out, Nacho's gone. That makes us somewhat deficient in defense. A weak backline cannot help you win titles. Perfect teams are continually striving for improvement and strength. We thus grab the chance to have a young stud like Saliba. He's a hungry kid who will inspire everyone to be better, not only a backup for Militao.
This goes beyond merely covering a void on the roster. It's about messaging the rest of the league. Our hometown is Real Madrid. Good enough is not what we accept. We go for the best. Always.
Real Madrid has already thought about these issues. They make transfers with the future in mind. That's why Real Madrid evaluates every possibility. I think after Nacho left the team, they immediately decided who to replace him with. Saliba is a young talent. If they bring him in, the team will continue their path without any problems in the future. There is only the defensive zone that will be felt missing right now. Ancelotti will be fully ready for next year after the most suitable transfers are made there.
